Claustrophobic and dangerous, that is the conditions a tank crew face on the battlefields in the 41st millenium. Lieutenant Commander Etsul and her crew are tasked with escorting a legendary figure through contested territory. Can they succeed once more?

The war for warp-cursed Croatoas rages on. Hailed as ‘Giant-killers’ for their heroics during Operation Jotunn, Lieutenant Commander Hadeya Etsul and the crew of the Leman Russ Demolisher Steel Tread are hurled right back into battle.
Assigned command of a convoy of armour and infantry, Etsul is tasked with escorting a legendary lord commissar through contested territory to stabilise the wavering Ruega Front. But with a new crew member disturbing the delicate harmony of her tank and a malevolent nemesis lurking unseen in the high passes ahead, the mission proves even more dangerous than first thought.
As Etsul’s troubles multiply she is forced to risk everything – even the hard-won trust of her crew – in the name of duty.
